Thats a DAU-9P cable. Spare yourself some problems and buy the cable. Its
about 1000 only.
You will need a MAX3232 chip for the cable (RS-232 to 3.3V CMOS level
converter). Last time I checked, this IC was in the 300-400 peso range at
R&I (dont know if Alexan carries it).
Plus, the aggravation of soldering (the MAX3232 is an SMD device AFAIK..
because what I've used is the MAX232 which is RS-232 to 5V TTL which is
DIL), errors and blunders connecting to the phone data port..
Note that the FBUS Rx/Tx pins used by the DAU-9P FBUS are right next to
the serial MicroWire Rx/Tx bidirectional pin used by the MBUS. The MBUS is
used for flashing the internal OS of the Nokia, etc. If you screw with the
MBUS, you can potentially destroy your phone.
So I suggest to just buy the cable. :)
Or, since you have a 6150, if your PC has an IrDA port you can use that.
The Data Suite supports it, so does gnokii.
